- Page 8: Remove the mounting plate of the old thermostat. Ensure the wires do not fall into the holes. Press the wiring backplate to the decorative cover plate to fix them together. It is suggested to use a decorative cover plate to cover the holes left on the wall by the old thermostat. Pass the wires through the hole in the middle of the wiring backplate. Fix the wiring backplate (and decorative cover plate) to the wall using wall plugs and wall mounting screws. Ensure the circuit of all related systems are shut off before installation. Remove the old thermostat from the wall and check if the power supply is 24VAC with a 2A maximum current. Do not power the WT201 thermostat with maximum current for a long time, which will damage the device. Disconnect the wires from the old thermostat and label the wires with stickers.
- Page 9: Hold down on the tabs to insert the wires into the holes of the corresponding terminals on the wiring backplate until they are firmly in place. If you need to release the wires again, hold down the terminal tabs. Adjust the DIP switch on the WT201 thermostat based on the connected wires. Download “Milesight ToolBox” App on an NFC-supported smartphone. Open “Milesight ToolBox” App and place the NFC area of the smartphone to the device. It’s suggested to change the default password for security reasons. Push the WT201 thermostat into the wiring backplate gently and ensure both parts are securely fixed. Turn on the systems to check if the WT201 thermostat is on. Download the ToolBox software from Milesight’s official website. Connect the WT201 device to a Windows computer via a type-C cable.
